摘要
工业硅烧穿器底盘组件作为整机的主体支撑结构,其性能直接影响工业硅烧穿器工作的可靠性。以工业硅烧穿器的底盘组件为研究对象,在保证结构静动态性能条件下,基于拓扑优化与响应面法结合对其进行轻量化研究。对底盘组件进行静态和模态分析,结果表明:底盘组件存在较大材料冗余,1阶固有频率有待提高;采用拓扑优化方法对底盘组件整体进行了结构优化改进;以质量最小、最大变形量最小和1阶固有频率最高构建目标函数,基于响应面模型和多目标遗传算法,对底盘组件进行多目标优化,优化后进行仿真验证,结果表明:底盘组件质量由优化前的2206.4 kg减小至1619.8 kg,减重比达26.59%,且1阶固有频率提高了12.25%,最大总变形量减小了1.43%,优化效果较好,满足轻量化设计要求。
The industrial silicon burner’s chassis assembly serves as the whole machine’s main support structure,whose performance directly affects the industrial silicon burner’s reliability.In this article,with focus on the industrial silicon burner’schassis assembly,a combination of topology optimization and the response surface method is used for the lightweight design,while ensuring the structure’s static and dynamic performance.The chassis assembly is subject to the static and modal analysis.The results show that there is a large material redundancy in the chassis assembly,and the first-order natural frequency needs to be improved.The chassis assembly’s overall structure is optimized and improved by means of topology optimization.The chassis assembly is subject to the multi-objective optimization,based on the response surface model and the multi-objective genetic algorithm,with the objective functions of the lightest mass,the smallest maximum deformation and the largest first-order natural frequency.After optimization,simulation verification is carried out.The results show that the chassis assembly’s mass reduces by 26.59%from 2206.4 kg to 1619.8 kg;the first-order natural frequency increases by 12.25%;the maximum total deformation reduces by 1.43%.This study has achieved desirable optimization effect and meets the requirements of lightweight design.
